Answer:
$835.20
Step-by-step explanation:
First you need to find out how many profit you had at first by multiplying 145 and $44.17.
So, 145*$44.17 = 6404.65
Then find out how much profit you had after it decreased by multiplying 145 and $38.41.
So, 145*$38.41 = 5569.45
Now to find how much profit you lost, you have to subtract $6,404.65 and $5,569.45.
$6,404.65 - $5,569.45 = $835.20
Answer:
are you using math solver app
For number 9 it's x+8= 14 and 7x=21
For number 10 the answer is that Beth is correct because the only number that could be replaced for x would be 2. There is no number besides 2 that you could put in the equation x+3=5 to get the answer 5.
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
